Description

2016 Batteries

• The CR2016 is a non-rechargeable (primary) lithium manganese-dioxide (Li/MnO₂) button/coin cell battery.

• Its naming convention “2016” indicates its size: 20 mm diameter and 1.6 mm thickness.

• Nominal voltage is 3.0 V.

• Typical capacity is around 75-100 mAh depending on manufacturer and load conditions.

• Typical weight is about 1.6-1.9 g.

• Operating temperature range is wide (for example –30 °C to +60 °C or even up to +85 °C according to some specs) depending on manufacturer.

• Self-discharge is extremely low (in some specs ~1% per year) making it suitable for long shelf-life applications

Key Features & Benefits

• Compact & Lightweight: The small coin size (20 mm × 1.6 mm) allows installation in thin, compact devices.

• Stable 3.0 V Output: Provides a steady voltage which is useful for devices requiring 3 V in a compact form.

• Long Shelf Life / Low Self-Discharge: Because of its chemistry and construction, it retains capacity even when stored for years.

• Wide Operating Temperature Range: Makes it useful in varied conditions (cold to moderately high temperatures).

• Low Internal Resistance for its size: Allows for efficient energy delivery in the devices intended.

• Safe and simple: As a primary (non-rechargeable) lithium coin cell, it is widely used and well understood.

• Versatile Applications: Because of its size and capabilities, it is used in watches, calculators, digital thermometers, key-fobs, small sensors/devices, etc.
